SHOCK-FORMING ATTACHMENT FOR GRAIN-BINDERS.

This invention relates to improvementsv in shock forming attachments for grain binders.

One object of the invention is tov provide. an attachment of this character adapted to receive the bundles of grain as they are bound and discharged from the machine and which when a sullicient number of bundles have been received will automatically discharge the bundles on end and in the form of shocks.

Another object is to provide an attachment of this character which will be simple, strong and durable in construction, efficient, reliable and entirely automatic in operation and which may be readily applied to binders now in use.

lith these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

gear for bringing the carrier back to a normal position; Fig. 7 is a horizontal sectional view taken on the line 7-7 of Fig.

6; F 1g. 8 is a detail perspective view of a portion of the attachment illustrating the means for holding the carrier in a normal position for receiving the shocks discharged from the machine.

My improved bundle forming attachment comprises a supporting frame consisting of a horizontally disposed bar or beam l which is secured by suitable brackets to the upper portion of the bundle conveyer frame F of the binder. The bar l has fixed thereto interminate its ends a right angular laterally projecting horizontal carrier supporting bar 2 on the outer .end of which is vsecured a depending vertically disposed arm 3, said arm being held rigid4 by a curved brace bar 4t connected theretoand to the bar 2 as shown. The bar l is preferably formed of channel iron while the bar 2 and arm 3 are preferably constructed of gas pipe or tubular metal bars. The frame when thus constructed is firmly supported by a cable 5 which is connected to the outer end of the bar 2 and extends inwardly and upwardly over a forked brace or prop 6 secured to the channel iron bar l. Said cable after passing from the prop G extends downwardly across the machine and has its opposite end suitably secured to the frame of the machine at its side thereof as shown.

Revolubly mounted in suitable bea-rings 7 on the bar l is a main drive shaft 8 having on one end a sprocket gear 9 which is connected by a short sprocket lchain 10 with a sprocket gear ll on the adjacent end of the upper conveyer shaft S of the machine, said conveyor shaft being geared to and driven by the ground wheel of the machine in the usual manner. Fixed on the shaft 8 intermediate its ends is a bevel gear pinion l2 with which is engaged a bevel gear 13 on the end of a right angularly disposed laterally projecting power transmitting shaft 14 which is revolubly mounted in suitable bearings on the bar 2 of the frame as shown. Loosely mounted on the outer end of the shaft 141 is a sprocket gear l5 having on the outer side of its hub a clutch member 1G which when the gear is shifted outwardl on the shaft la is adapted to be brought into engagement with a clutch member 17 fixed on the outer end of the shaft whereby the sprocket gear is locked to and driven by the shaft for apurpose hereinafter described.

Fixedon theV power transmitting shaft 14 intermediate its ends is a bevel gear pinion 18 which has an operative engagement with a large bevel gear 19 which is revolubly mounted on a short stud shaft 20 arranged on the bar 2 as shown. The gear 19 is provided with a crank pin 21 to which is pivotally connected the upper end of a bundle throwing arm which projects downwardly bet-Ween and is slidably held in position by two guide. rollers 23 which are adjustably mounted inv a segmental bar or bracket 24 which is secured to the curved brace 4 of the supporting frame as shown. On the lower end of the arm 22 is a plate 25 having formed thereon forked bundle engaging hooks 2G which are adapted to engage the bundles as they leave the discharging mechanism D of the binder and to throw said bundles over into the carrier of the attachment as will be hereinafter more fully described. The plate 25 is hingedly connected at its inner end to the arm 22 and is held in yielding' engagement therewith by a bolt 27 having thereon a coiled spring 2S which is arranged between the plate and the thumb nut 29 on the bolt whereby the pressure of the lspring is adjusted to yieldingly hold the plate'25 against the end of the arm and to permit the hooks of the plate to have a yielding engagement with the bundles. Y

lPivotally mounted in the depending arm 3 of the frame near its lower end is an eye bolt 30 in the outer end of which is secured the main bar 31 of the bundle carrier 32. The bar 31 is of suitable length and is preferably constructed of gas pipe or similar metal tubing and said bar is connected to the eye bolt nearer the rear end of the bar than the forward end whereby when the bar is released the forward end thereof will overbal` ance the rear end and cause the bar to swing to a vertical position as will be hereinafter more fully described. The bundle carrier 32 is preferably in the form of a cradle and comprises a series of curved fingers 33 which are spaced apart and secured at their outer ends in the bar 31 as shown. rlhe fingers 33 project inwardly toward the machine and are arranged in parallel position to receive the bundles thrown thereon by the hooks 2G on the end of the bundle throwing arm 22 hereinbefore described. On the shorter end of the bar 31 is an offset bracket 34 the outer end of which is connected to a brace plate 35 which is pivotally connected to the inner end of the eye bolt 30 to which the bar 31 of the carrier is connected. Tothe opposite end of the bar 31 is secured an offset bracket 36 to which is connected one end of a carrier retracting chain 37 which passes upwardly around a guide pulley 38 revolubly mounted in suitable bearings 39 on a. stop plate 40 which is secured to and supported at the front end of the carrier by a suitably braced supporting arm 41 which is connected to and projects forwardly from the arm 3 of the carrier supporting frame. The purpose of the .stop plate 40 will be hereinafter described. The chain 37 after passing around the guide pulley 33 -extends upwardly and over the sprocket gear 15 which is loosely mounted on the outer end of the power transmitting shaft 14 and from said sprocket gear 15 the chain extends downwardly and has its end connected with a tension rod 42 which is slidably engaged with au apertured guide lug 43 arranged on the bracket 34 secured to the shorter end of the bar 3l. rPhe lower end of the tension rod 42 is threaded and has thereon a nutand between said nut and the lug 34 is a coiled spring 44 the pressure of which is exerted to keep the chain 37 taut and to impart the proper tension thereto.

Mounted in a suitable bearing 45 secured to the outer side of the main bar 3l of the carrier is a short crank shaft 40 having on one end an inwardly extending curved bundle engaging arm` 47 which projects over the bundles deposited onto the carrier. On the opposite end of the crank shaft 46 is a short c 1ank arm 4S to which is connected a rod 49 which extends upwardly through an apertured guide block 50 secured to the brace 51 of the supporting arm 4l. The outer end of the rod 49 is threaded and has screwed thereon a nut 52 between which and the block 50 is arranged a coiled spring 53 the pressure of which is exerted to yieldingly hold theV rod 49 so that when a sufficient number of bundles have been deposited onto the carrier and the latter has been released in the manner described and has started to swing dowm 7ardly for depositing the bundles in a shock the downward movement of the carrier will cause the crank arm 48 on the shaft 4G to pull against or yieldingly hold the spring retracted rod 49 thereby causing said rod to rock the shaft 4G and swing the bundle gripping arm 47 downwardly against the, bundles in the carrier thereby iirmly holding said bundles until the carrier has swung downwardly to a position for depositing the bundles on the ground. By this ar 1angement it will be seen that the bundles will be kept, together in the carrier while the latter is being tilted so that all of the bundles are discharged from the carrier at the same time and will remain in a standing position supported by each other in the form of a shock when discharged from the carrier. At a suitable position in the rod 49 is arranged a stop pin 5ft which is adapted to engage the guide block 50 through which the rod 49 slides thereby limiting the retracting movement of the rod by the spring 53.

The butts of the bundles when thrown into the carrier come into engagement with the stop plate l0 and by means of said plate the butt ends of the bundles are squared up and they are prevented from falling out of the carrier. W'hen the carrier is swung to a vertical position for discharging the bundles the movement of the carrier is limited by a hook shaped stop 55 aranged on and projecting laterally from the lower end of the arm 3 in the path of movement of the bar 3l of the carrier as shown. Secured to the bar 3l of the carrier on opposite sides of its pivotal connection with the arm 3 is the forked lower end of a carrier holding bar 5G which projects upwardly adjacent to the outer side of the arm 3 and has on its upper end a stop linger 57 on which is revolubly mounted a guide roller 5S which is adapted to travel on a segmental track plate 59 secured to the upper portion of the arm 8 and to the plate supporting arm 4l as shown. By arranging the bar 56 and the roller 5S as herein shown and described it will be seen that when the carrier swings to vertical horizontal positions that the roller 5S will engage and travel on the track plate 59, thus relieving` the eye bolt 30 which supports the carrier7 from a torsional strain which would be applied thereto by the weight of the load of bundles on the laterally projecting fingers of the carrier. The engagement of the roller 5S with the track plate 59 will also obviate any tendency of the bar 3l to turn in the eye bolt which supports the same.

The carrier is held in a horizontal position to receive the bundles thrown therein from the discharge mechanism of the binder by a detent. or stop pin G0 which has a sliding engagement with a transverse aperture in the upper portion of the arm 3 and which is yieldingly projected and held in a projected position by a flat spring Gl secured to the arm 3 and having an operative engagement with a stud G2 on the inner end of the stop pin as shown. By means of the spring (il the outer end of the stop pin is projected 'ni the path of movement of the stop finger 57 on the upper end of the bar 56 thereby holding the carrier in a horizontal position for receiving the bundles discharged from the machine.

lin order to retract the stop pin (30 and to thereby permit the carrier to tilt and discharge the bundles carried thereby, l provide an automatically operated pin retracting mechanism comprising a rod 63 which is connected at one end to the inner end of the pin (30 and guided in a bracket G4 on the carrier supporting bar 2 as shown. Adjustably secured to the rod 63 near its inner end is a tappet` block 65 which 1s adapted to be engaged by a tappet stud 66 arranged on and projecting laterally from one side of a ratchet gear G7 which yis revolubly mounted in a bearing bracket 68 on the brace 4f of the carrier frame as shown. Loosely mounted on one end of the shaft of the ratchet gear 67 is a lever G9 having thereon a spring pawl 70 which is adapted to engage the teeth of the ratchet gear 67 whereby when the lever 69 is rocked a step by step movement will be imparted to the ratchet gear. The lever 69 is actuated by a rod 7l the upper end of which is adjustably connected to the lever in one of a series of apertures formed therein while the opposite end of said rod is pivotally connected to the outer end of a short crank arm 72 tired on the shaft of the rotary disk 73 which carries the bundle kicking` arm 74 of the bundle discharging mechanism of the binder. By thus connecting the lever with the bundle discharging mechanism it will be seen that at each revolution of the disk 73 the lever will turn the ratchet gear 67 for the distance of one tooth. Then the ratchet gear is thus turned to bring the stud 66 thereon into engagement with the block G5 on the pin retracting rod 63, the movement of the latter will retract said stop pin thereby permitting the carrier t0 tilt and discharge the bundles therefrom in the manner described. By constructing the pin retracting mechanism as herein shown and described it will be seen that by varying the adjustment and relative sizes of the parts or by providing Vthe ratchet gear with two or more tappet studs, the stop pin 60 may be retracted to permit the carrier to tilt at any desired time or when any desired number of bundles have been deposited therein.

After the stop pin 60 has been retracted and the carrier permitted to tilt and discharge the contents thereof the carrier retracting mechanism is automatically thrown into operation to swing the carrier back or to restore the same to its normal position for receiving the next load of bundles. The means for automatically throwing the carrier retracting mechanism into gear comprises a rock shaft 75 which is mounted to turn in suitable bearings 7G arranged on the outer side of the main bar 3l of the carrier. On the inner end of the rock shaft 75 is formed a downwardly and inwardly curved trip arm 77 which projects between two of the bundle supporting fingers of the carrier and which is adapted to be engaged by the bundles thrown onto said lingers. On the outer end of the rock shaft 75 is formed an offset or cam projection 7 8 which, when the trip arm 77 is released by the discharge of the bundles from the carrier, is adapted to be turned by a torsional spring 79 arranged on and connected at one end with the shaft 75 and at its opposite end with the bar 3l. The offset or cam projection 7S when thus turned is brought into izo engagement with a plate 80 on the lower end of a gear shifting lever 81 which is pivotally mounted in a supporting bracket on the upper end of the arm 3 and provided with a forked upper end having a loose engagement with the annularly grooved hub of the 4sprocket gear 15 whereby the latter is shifted outwardly and the clutch member 1G thereon brought into engagement with the clutch member 17 fixed on the shaft let, thus causing said shaft to turn the sprocket gear l5, thereby moving the chain 37 Vin the proper direction for swinging the carrier upwardly t0 a horizontal position.

The plate S0 is hingedly connected at its upper end to the clutch shifting lever Sl and has its lower end projecting a slight distance below the lower end of the lever, said lower end of the plate being held in yieldying engagement with the lever by a coiled spring 82 arranged on a bolt S3 which projects laterally from the lower end of the lever and through a slot in said plate. The tension of the spring is regulated by a thumb nut 84 on the end of the bolt 83 as shown. TWhen the chain 37 has swung the carrier upwardly to a horizontal position the roller 5S on the stop finger 5T of the bar 5G will be brought into engagement with the inner side of the plate 80 thereby forcing the latter' and the lower end of the gear shifting lever Sl outwardly and its upper end inwardly, thus shifting the gear on the shaft 14: and disengaging the clutch member of the gear from the clutch member on the shaft which will thus disconnect the shaft from the gear and immediately stop the operation of the latter.

From the foregoing` description taken in connection with the accompanying drawings', the construction and operation of the invention will be readily understood without requiring a more extended explanation.
